TL;DR
A bat exclusion cone is a smooth one-way tube or netted funnel mounted over a building's bat entry hole that lets the colony fly out at dusk but gives them no grip to land and crawl back in. It is the humane core of bat exclusion, used because poisoning bats is illegal and trapping is impractical; after several nights of zero activity the device comes off and the opening is sealed permanently.
What it means
A bat exclusion cone is a smooth one-way tube or netted funnel mounted over a building's bat entry hole that lets the colony fly out at dusk but gives them no grip to land and crawl back in. It is the humane core of bat exclusion, used because poisoning bats is illegal and trapping is impractical; after several nights of zero activity the device comes off and the opening is sealed permanently. Timing is regulated: installation is prohibited during the summer maternity season, roughly May through August in most states, when flightless pups would be sealed inside. Wildlife-control bids should list one of these per active opening plus the final sealing visit.
